BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a vise, and more particularly to a
vise with an adjustable operating angle.
2. Description of Related Art Including Information Disclosed Under
37 CFR 1.97 and 37 CFR 1.98
A conventional vise has a fixed seat such that a wedge washer is
provided under the workpiece such that the workpiece is inclined
relative to the fixed seat when the workpiece needs to be processed
at a specific angle. However, the standards of the wedge washer are
limited such that the main shaft of the processing machine also
needs to be adjusted. It is inconvenient to the conventional vise
when the workpiece needs to be processed at a specific angle.
In view of this, some vises with an adjustable operating angle are
on the market for adjusting the operating angle of the workpiece by
the structures of the vise. The conventional vises have two
adjusting types including swing left and right relative to two
opposite sides and swing back and forth relative to two opposite
ends. As well known, a distance between two opposite ends of the
vise is greater than that between the two opposite sides of the
vise. As a result, the vise, in the type of swing back and forth,
has a greater adjusting range and the adjusting range may intervene
the operating room of the processing machine.
